Summary

Identifying predictors of mortality in elderly patients is crucial. Poor functional status, male gender, low albumin, and specific clinical scores independently predict 6-month mortality after hospitalization.

Area of Science:

  • Geriatric Medicine
  • Clinical Epidemiology
  • Internal Medicine

Background:

  • Hospitalized elderly patients often present with high disability and multiple chronic conditions (polypathology).
  • Multidimensional and functional assessments are vital for identifying risk factors associated with clinical and functional decline.
  • Predicting high-risk patients is essential for effective patient management and resource allocation.

Purpose of the Study:

  • To identify independent predictors of 6-month post-hospitalization mortality in elderly patients admitted to a Geriatric ward.
  • To evaluate the prognostic value of functional status compared to diagnoses in this population.

Main Methods:

  • A cohort of 395 hospitalized elderly subjects (mean age 77.9 years) was assessed.
  • Data collected included demographics, medical diagnoses, functional evaluations (Dependence Medical Index, Instrumental Activities of Daily Living), and laboratory values (serum albumin).

  • The Acute Physiology and Chronic Health Evaluation (APACHE II) score was also recorded. Mortality was tracked for 6 months post-discharge.

    • Main Results:

    • A total of 80 subjects (20.2%) died within 6 months.
    • Independent predictors of mortality included male gender, high dependence (DMI), low serum albumin (< 2.8 g/dl), impaired Instrumental Activities of Daily Living (IADL) score, low APACHE II score (< 13.7), and a diagnosis of neoplasm.
    • Poor functional status emerged as a more reliable prognostic indicator than the type or number of admitting diagnoses.

    Conclusions:

    • The high mortality rate highlights significant frailty in the studied elderly population.
    • Functional status assessment is a practical and effective tool for identifying elderly patients at high risk of short-term post-hospitalization mortality.
    • Integrating functional status into clinical evaluations can improve risk stratification for hospitalized older adults.
